Abstract Heart failure (HF) is a growing public health concern, with red cell distribution width (RDW) gaining recognition as a cost-effective marker for predicting HF onset and progression. This study, conducted from February 2022 to February 2024 at Hue Central Hospital, aimed to assess RDW levels in hospitalized Vietnamese HF patients and its predictive value for HF severity, involving a cross-sectional analysis of 351 patients categorized into HF and non-HF groups. HF patients exhibited higher median RDW levels (14.90% 13.70% - 17.00%) compared to non-HF individuals (13.10% 12.23% - 13.78%). RDW was higher in HF patients with left ventricular ejection fraction (LVEF) 13.85% were independent risk factors for AHF. This suggests that RDW levels can serve as biomarkers for diagnosing HF and predicting its severity. Their accessibility and cost-effectiveness indicate the potential utility of RDW in managing HF, particularly in settings with limited resources.
